Hi all, have a small dilemma with my 360 block, the oil passage on #5 in the block that meets with the oil pump passage in the cap has a small piece cracked out of it. Not sure what to do here, do i pull the piece out, clean it up a little and run it, any problems with the bearing or oil leakage?
Anyone ever had this problem. please help
Will post up some pics.

not sure how to put pics up now as photobucket crap. i'll get back with some pics when I can work this out.

i am no expert when it comes to building engines, but i definitely would not allow that tiny piece to stay there, in case it would break off and migrate to a place that would block off oil flow, or cause damage by getting caught in rotating pieces. my first instinct would be to remove it and be very accurate in smoothing out the area, but how would that tiny area affect the bearing crush ? others more in the know than i should answer this question. i will be observing this post for answers to add to my knowledge base.

Break it out, press in a piece of the appropriate size tubing to sleeve it, leave the sleeve a little high and have the cap receive it. Clean out, and put it together. My

I'm not sure you even have to sleeve it, but yes break the piece off. And if you can sleeve it, that's the best fix.

Just another issue with the bigger mains of the 360.

That small piece is definitely distorting the bearing fitment. See if you can knock it back flush. If so, and it is captured by the main cap, bearing shell and can't fall back into the bolt hole or go anywhere. You can run it with no migration or bearing distortion issues with a very high probability that it will be like that when you pull it apart for the next rebuild.

That's what I'd do, break off the piece and run it as is.

Thanks all for your advice, after looking at it again with the bearing and main cap on and torqued up the piece did flatten out and is encapsulated in its spot, I then pulled the cap and grabbed hold of the piece thinking it would just pull/fall out but instead it was tight, so I'm thinking about leaving it in place( yeah crazy I know ).

If its like the old broken pencil fit and the cap secures it id almost run it but really as mentioned it would take $3 for a foot long tube (u might need 3 inches of it, and 10 minutes to install and trim.

I did look at your pic, if you remove it I wonder what 60psi on that area would do if anything?

Why not just tube it and move on with no worries?

As well you mention its tight, ive found countless number of sand clumps on heavily used and raced blocks that never released until forced.

How did that happen, the guy who align honed it? Or did someone use that hole to pry against?

that's what I would do. I caused that by grabbing a mini freeze plug that was a c hair too big. I tapped the broken chunk back into place & no issues
